The video is taken from a vehicle driving through downtown Moscow in the early hours of February 28, when Nemtsov was killed.

About 48 seconds into the video, the car drives over Bolshoi Moskovoretsky bridge, where Nemtsov’s body was found, and overtakes a white vehicle and a lorry. There are not many people around the scene, but according to the Guardian, that is the spot where the murder took place.

Here is a screengrab of the scene, with the timestamp in the bottom left corner:
